FIELD OF THE INVENTION

The present invention is directed to providing an exercise device, particularly a compact and portable device for performing more effective push-ups.

BACKGROUND OF THE INVENTION

The Push-Up is one of the world's oldest exercises and is one of the best ways to strengthen and build up upper body strength, including chest, shoulders, arms abdomen and lower back muscles when done correctly. In particular, push-ups are a favorite exercise for developing strength in biceps, triceps and abdominal muscles, for body-building, fitness and for weight control.

Conventional push-ups are performed whilst lying chest-down with hands at shoulder level and palms flat on the floor and slightly more than shoulder-width apart and feet together and parallel to each other. Keeping the legs straight and toes tucked under the feet, the arms are straightened to push the body up off the floor. Keeping the palms fixed at the same position and the body straight without bending or arching the upper or lower back while pushing up, the exerciser should exhale as the arms straighten out. After a momentary pause, the exerciser slowly lowers the body towards the floor. Bending the arms while keeping the palms in a fixed position and keeping the body straight and feet together, the body is lowered until the chest touches the floor. Without bending the back, the knees are kept off the floor, the exerciser inhaling as the arms are bent. After pausing for a moment, the exerciser straightens the arms for a second push-up, exhaling whilst raising the body.

Indeed, push-ups and pull-ups are all that is needed to work the major upper body muscle groups. Members of the US Armed Forces, especially the army and the Marines, still depend on these two exercises, along with crunches and running, to stay in shape when they're stationed in a locale without a training facility.

There is, however, a known limitation with using just push-ups and pull-ups for upper body training that arises as the trainee's strength plateaus, in that with any exercise, whether using one's own body weight, free weights or machines, if the resistance doesn't increase, the muscles are not overloaded and the stimulus these fibers need to grow in size is missing.

There are, however, a few ways that have long been known, for increasing the resistance of pull-ups and push-ups. One way is to elevate the feet while doing push-ups. Essentially, one starts with the feet on a step at the bottom of a stair or a low step stool. Raising the feet higher make one work against gravity, thereby increasing the resistance. Ideally one should work up to the point where one can perform push-ups with one's feet on a chair. It will be noted that the higher the feet, the more work is done by the shoulders.

Other variations for improving strength and muscular endurance include modified push-ups with hands on an object or with feet on an object. With hands on an object, the difficulty of the exercise may be increased by first placing the hands on a wall, later on a desk, then on a chair (or by progressing to lower stairs on a staircase). By progressing to lower levels of hand placement, the intensity of the exercise is increased with a resultant increase in muscle strength.

With feet on an object, the body is kept straight with hands on the ground and feet on a chair, steps, or some object. Progressively elevating the feet to higher levels increases the intensity of the exercise. The difficulty and hence strength may be further increased by doing push-ups between chairs with the feet elevated; the exerciser lowering himself/herself as far as possible between the chairs.

A push up device comprising a hand unit and a separate foot unit coupled therewith is described in co-pending application number U.S. Ser. No. 11/467/680 to Shtorch, for which a notice of allowance has been received. The device addresses many of the issues described hereinabove, but, though to some extent foldable, nevertheless takes up space, since it consists of separate hand and foot support structures.

Equipment for facilitating variations to standard exercise techniques are known. For example, U.S. Pat. No. 6,780,144 to Stevens, entitled Segmented Weight and Exerciser describes an exercise device which has a hub, a flat strap having one end connected to the hub and adapted to be wound on the hub, a handle connected to an opposite end of the strap for allowing a user to hold the handle to support the hub and a pair of disk-shaped weights connected to opposite sides of the hub. In one embodiment of this device foot pedals are provided which a user can push against while seated upon the floor. This device provides various exercising possibilities but is not suitable for performing push ups.

Another exercise apparatus is described by Riazi in US2006/0040808. Riazi's apparatus is configured to be used in conjunction with an exercising ball, and describes a base configured to stabilize the rolling movement of an exercise ball under the influence of a user seated on the ball. The base defines a range in which rolling movement of the ball is unimpeded, and has an obstacle portion configured to impede rolling movement of the ball beyond that range. This enables the base to stabilize the ball and the seated user when the ball rolls into contact with the obstacle portion of the base. By their nature, push ups require that an exerciser's weight be supported at least in part by his hands. Razi's apparatus is configured for an exerciser seated upon a ball and thus is not compatible with performing push ups.

A further known exercise device is presented in U.S. Pat. No. 6,626,807 to Richmond describing first and second platforms respectively provided for supporting a user's arms and knees. Rollers on the bottom surface of at least one of the units facilitate relative movement between the units. Embodiments are described which include various units for supporting the hands and feet including a detent to receive the user's legs or to retain the user's calves or ankles on the unit and a unit for receiving and retaining the user's feet which may be disposed on a rod the length of which being adjustable to the dimensions of the user.

Richmond's exercise equipment provides platforms which move relative to one another. Such movement is not necessary when performing a push up and indeed makes the performance of standard push ups extremely difficult. Moreover, when performing standard push ups the knees are kept off the floor, therefore in order to perform push ups, an exerciser would be required to dismount from Richmond's exercise equipment.

U.S. Pat. No. 6,945,919 to Yang. Yang describes a balance-exercising apparatus with an inflatable semi-spherical section and an annular frame connected on two diametrically opposed points with two movable pulling ropes. For normal use a user holds the pulling ropes and treads, jumps, sits or lies on the air cushion. FIG. 6 of U.S. Pat. No. 6,945,919 shows the device being used to raise the hands of an exerciser performing push ups, however in Yang's device the height of the hands is fixed by the height of the semi-spherical section and is not easily adjusted. Indeed as outlined above, any object, such as a stool, step or chair could be similarly used to raise the hands during performance of a push up, and Yang's equipment does not contribute to the effectiveness of the exercise.

U.S. Pat. No. 5,582,565 to Soria describes a triceps exercise apparatus wherein a pair of adjacent hand grips receive the user's hands in an overhand grip and are formed from a generally horizontal bar whose height is adjustable but is approximately set to 19.5 inches above the level of the user's feet. The device allows a user to grip the bar with his or her arms above his or her head and his or her body facing downward. The apparatus includes a block for receiving the feet of the user and a means for manually adjusting the distance of the block from the bar so as to adjust the apparatus to users of differing heights. Soria's apparatus facilitates a particular pull up exercise which targets the development of the triceps for boxing and although it could be used for performing push ups with the hands raised, it does not provide any means of raising the feet above the level of the hands, which is required to increase the effectiveness of the push up exercise for developing biceps.

A device for performing push-up exercises is described by Bergman and Jahanian in U.S. Pat. No. 7,060,014. This describes an exercise machine which has a body support platform extending at a variable angle of inclination from a point of rotation. A user lays prone on the body support platform to perform a push-up. When a person laying on the body support platform performs a push-up, the body support platform rotates around its point of rotation. A bias mechanism is used to bias the body support platform toward one angle of inclination. Depending upon the needs of the user, the bias mechanism can be configured to either apply an upward bias to the body support platform that would assist a person in performing a push-up, or apply a downward bias to the body support platform that would resist a person in performing a push-up. U.S. Pat. No. 7,060,014 does not provide a method for raising the feet above the head but supports the whole length of the body with the head raised above the feet. In addition the device described therein is bulky and not readily adjustable for exercisers of different heights. Since the pivot is below the feet U.S. Pat. No. 7,060,014 also requires more space than for regular press ups.

There is a need for a compact apparatus for assisting an exerciser to perform standard push ups, where stairs, stools and the like are unavailable. Such an apparatus preferably provides controlled modular increase in difficulty and effectiveness for building up muscles, fitness and stamina. The present invention addresses this need.
